#include<stdio.h> int main() { int p, num, rev = 0, rem; int n = 1; for(int a = 2; a < 20; a++) { for(int b = 2; b < 20; b++) { p = a * b; num = p; rev = 0; while( num > 0 ) { rem = num % 10 ; rev = rev * 10 + rem ; num /= 10 ; } if(p == rev) { printf("%d. palindrome = %d\n", n, p); n++; } } } return 0; } Corrected the code, you need to initialize rev to 0 after each termination of while loop.

But why do we have to initialize rev=0, I mean how does it matter. Value of rev will b changed after each iteration. ūü§Ēūüßź
